SPECIFICATION forming part of Letters Patent No. 589,668, dated September 7, 189

Application filed April 2, 1897. Serial No. 630,338- (No model.)

To aZZ whom it may concern Be it known that we, HARRY S. NOBLE and GHARLEY MTossme, of St. Marys, in the county of Auglaize and State of Ohio, have invented a new and Improved Wrench, of which the following is a full, clear, and exact description.

This invention is a wrench of that class in which the wrench has a fixed and a sliding jaw, and means coactin g with the sliding jaw by which the sliding jaw may be held at any adjustment within the range of the movement of the sliding jaw.

This specification is the disclosure of one form of our invention,while the claims define the actual scope of the conception.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate correspondingparts in all the figures.

Figure 1 is a side elevation of our invention. Fig. 2 is a sectional View thereof. Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2. Fig. 4c is a perspective view of aportion of the movable jaw, and Fig. 5 is also a section on the line 3 3 of Fig. 2 and showing the parts in different position.

The wrench has a handle 6 to which a shank 7 is fixed. The outer endof the shank 7 carries the fixed jaw 8. The sliding jaw 9 runs on the shank 7 and has a shifting tiepiece 10 to permit the recovery of the grip of the wrench on the pipe or other round object.

The major portion of the shank 7 and that portion which is adjacent to the handle 6 is formed round and provided with a ribll, running longitudinally throughout its length. Running spirally around the rounded port-ion of the shank 7 are a series of broken threads 12, thelengths of which are equal and amount to a little over one-half the circumference of the rounded portion of the shank 7 The outer edges of the threads 12 are within the diameter of the large or outer portion of the shank. This large or outer portion of the shank is angular, so that the jaw 9 will not turn on the shank.

The jaw 9 has an inwardly-running flange l3, curved in the arc of a circle and fitting loosely within an. annular groove 14, formed on the front portion of the thimble 15. The t-hiinble 1.5 is provided with aseries of threads threads 12, so as to hold the thilnble l5, and

consequently the jaw 9, at any position on the shank. hen the threads 16 are in the position shown in Fig. 3, the thiinble 15 will be free to slide along the shank. To hold the thinible in this position, the operator should turn the t-himble until the threads 16 engage with the side of the rib 11, which side is opposite the side on which the threads 12 are located. This will keep the thiinble in the proper place and permit it to slide freely. hen it is desired to lock the sliding jaw, the thinible is turned oppositely to the direction above described, so that the threads 16 will engage with the threads 12 and the thimble with the jaw 9 will be locked firnilyon the shank.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a wrench, the combination of a shank with a rigid jaw fixed thereon and a shank with a series of broken threads at one side of which a rib runs longitudinally along the shank, a jaw sliding on the shank, and a thimble revolubly connected with the jaw and turning on the shank, the thiinblc having broken internal threads coacting with the threads on the shank.

2. The combination of a shank having broken threads at one side of which a rib runs longitudinally with the shank, and a thimble turning on the shank and having internal threads coacting with the threads on the shank.

3. The combination of a shank with a rigid jaw thereon and with broken threads at one side of which is a rib running longitudinally with the threads, a jaw sliding on the shank, and a thinlble revolubly connected with the jaw and having internal threads coacting with the threads on the shank.

4c. The combination of a shank having a series of broken threads, the lengths of which are separated from each other to form a 1011 gitudin al space running along the shank, and the shank also having a rib running longitudinally at one side of the threads, and a thimble turning on the shank and having broken internal threads coacting with the threads on the shank, the threads of the thimble being capable of moving through the space between the ends of the threads on the shank when not engaging said threads on the shank.

5. The combination of 'a shank having" broken threads, with a stop at one side of the threads, the ends of the threads being separated to form a space running longitudinally along the shank between the ends of the running through the space between the ends I5 of the threads on the shank.
